Abstract

POTT, A; OLIVEIRA, AKM; DAMASCENO-JUNIOR, GA  and  SILVA, JSV. Plant diversity of the Pantanal wetland. Braz. J. Biol. [online]. 2011, vol.71, n.1, suppl.1, pp. 265-273. ISSN 1519-6984.  http://dx.doi.org/10.1590/S1519-69842011000200005.

This is a review of current studies in diversity of the flora and main vegetation types in the Brazilian Pantanal. The flora of this wetland, nearly 2,000 species, constitutes a pool of elements of wide distribution and from more or less adjacent phytogeographic provinces, such as Cerrado, dry seasonal forests, Chaco, Amazonia and Atlantic Forest. The most numerous group includes wide-distribution species, mainly herbs, while the second contingent comes from the Cerrado. Endemic plants are rare, numbering only seven. The vegetation of the sedimentary floodplain is a mosaic of aquatics, floodable grasslands, riparian forests, savannas (cerrados), cerrado woodlands, dry forests, and a large area of mono-dominant savannas, and pioneer woodlands. The main vegetation types are briefly described with their characteristic species, and their estimated areas are given according to the latest mapping.

Keywords : Cerrado; Chaco; flora; forest; savanna.
